Sure. The premise is that there can't be a civilization without domesticated crops and animals. So the first step is to genetically trace the major crops in the world today back to their wild origins. Then we look at when they started flourishing. Now we have a rough idea of time and areas to begin looking. And, when we look at how the first civilizations we know of started and spread, we know what clues to look for to indicate an earlier civilization. Bottom line, there was no Atlantis. Without agriculture, a society can't create the permanent specializations of its population needed to make advancements. The main crops we eat couldn't have flourished before the end of the last ice age, and the timeline for a civilization developing from the beginnings of crop domestication is 5000 years at the least.

good vid. did you know that there are old islamic tales of a similar city. that existed before humans were ever put on earth. the earth was given by god to a race called gin/jinn later on god sent an army of angels to drive them into the sea, before he put humans here. these stories predate any greek stories about atlantis and are worth looking into
